Grow tent, 3x3 ventilation temperature issue

[User1534]

Cant you just dim the light down? If you cant, just get a cheap t5 floro to start your plants.

Where are these bought at locally? Links would help

I know you arent asking me, but in the winter my nite temps are 65, summer 75. Never had a problem either way

How are you setting up your lights? 12/12? What’s the temp with lights off

Just flipped to 12/12. Lights off 74-76

Home depot. Its just a fluorescent fixture. Any will do, doesnt need to be for growing

Checking my temps with the light off now, but thats achieved throughout the entire grow? 74 with lights off throughout the whole grow?

All information is what I’m looking for! And these are temps outside or inside grow area??

 

[SBBCal]

Doesn't that light have a bloom switch too? I'd personally keep both on even during your stage. Just me though

My fans run all the time, so when the lights are off, that is the temp inside

Yup, I don't let it get lower than 70 though. I run lights on at night. 9pm-8:30am. Helps keep temps in check here in California and also the ladwp bill. Fuckin bastards

I was thinking of getting a tiny space heater for winter to keep it above a specific temperature. You say the best temp at minimum with lights off would be 70 degrees?

 

[User1534]

My temps are sitting at 78 with the lights off so far.

You probably dont even need anything that big. I used to use a 2 bulb desk lamp to cover a dozen seedlings

 

[SBBCal]

Yeah i wouldn't let it drop past 70. I'd also heat your room not the tent. Let the intake suck in the warmer air

Your just putting 2 fluorescent bulbs over them? Wow

They are just seedlings. They will grow fine for a week or 2, and not stretch much if the light is close enough.

Perfect. I’m gonna go get it right now and get them going for the time it needs.

I was trying to explain it to you but my boton

where are your thermo/rh meters at? I keep one at canopy level and one at the pots level. Both off to the side away from direct light. That way you can average both temp/rh with both readings
